- Make class Student, you need to add the normal constructor with parameters not default with 5 attributes age, gender, ID full name, date of registration JAVAExtend the ItemToPurchase class per the following specifications: Private fields string itemDescription - Initialized in default constructor to "none" Parameterized constructor to assign item name, item description, item price, and item quantity (default values of 0) Public member methods setDescription() mutator & getDescription() accessor printItemCost() - Outputs the item name followed by the quantity, price, and subtotal printItemDescription() - Outputs the item name and description Ex. of printItemCost() output: Bottled Water 10 @ $1 = $10 Ex. of printItemDescription() output: Bottled Water: Deer Park, 12 oz.For the 'The Chicken class' on the app intelliJ in java. The Chicken class must:• Define three fields called exactly name, pricePerKilo and inStock. The name field must be of type String, the pricePerKilo must be of type int (representing the cost per kilo in pence) and the inStock field must be of type boolean.• Initialise the three fields via a constructor that takes exactly two parameters. The first parameter must be of type String and the second parameter must be of type int. The first parameter must initialise the name field and the second must initialise the pricePerKilo field. The constructor must set the inStock field to true for all Chicken objects. There must be no parameter to the constructor for the inStock field.• Define getters for all three fields using the standard getter naming convention. In particular, note that the getter for the inStock field must be called getInStock rather than isInStock.• Define setters for the pricePerKilo and inStock fields using the standard…

- Given the following class, I need help writing a constructor that initializes all instance variables using appropriate parameters. I need to make sure it enforces the preconditions public class BrowserTab {private String title;private int id;/*** Creates a BrowserTab* @precondition title != null && id >= 0*/}IN C++ Implement a class Car with the following properties. A car has a certain fuel efficiency (measured in miles/gallon or liters/km—pick one) and a certain amount of fuel in the gas tank. The efficiency is specified in the constructor, and the initial fuel level is 0. Provide another parameterized constructor which takes both efficiency and fuel as parameters. Also supply methods getGasInTank, returning the current amount of gasoline in the fuel tank. getEfficiency() return the efficiency of car. setGasInTank(double fuel), to add gasoline to the fuel tank. setEfficiency(double efficiency) Supply a method Drive () that simulates driving the car for a certain distance, reducing the amount of gasoline in the fuel tank according to its efficiency. Sample usage: Car myHybrid (50); // 50 miles per gallon myHybrid.addGas(20); // Tank 20 gallons myHybrid.Drive(100); // Drive 100 miles double gasLeft = myHybrid.getGasInTank(); // Get gas remaining in tank Supply a main method that tests…How many parameters must be passed if only the following prototype is given to a constructor?Prototype: className(int x, int y, int z=0); 1 2 3 Compile time error
